Detective Comics #300
☆ Be the first to review + Add to your collection — Join freeDetective Comics #300 marks a triple-digit milestone in one of DC's longest-running titles — the very series that gave the company its name and introduced Batman back in 1939. Its chief claim to historical significance is the debut of Mr. Polka-Dot (later Polka-Dot Man), a gimmick-driven Silver Age villain who embodied the era's cheerful willingness to build an entire crime wave around a single visual motif, complete with detachable dots that transformed into flying saucers, buzz-saws, and escape capsules. The issue also quietly closes the book on Aquaman's Detective Comics residency, a structural editorial shift that handed those pages to the Martian Manhunter feature instead. Decades after the character was dismissed as one of Batman's sillier rogues, James Gunn's 2021 film The Suicide Squad rehabilitated the Polka-Dot Man into a tragic, fully realized figure — sending collectors and historians back to this issue as the source point for that unlikely cultural redemption.
In "The Bizarre Polka-Dot Man," Aquaman and Aqualad answer a desperate call for help when Professor Peters vanishes during a treasure hunt. With perilous underwater dangers at every turn—including a crushing rock slide and a deadly whirlpool—Aquaman uses his command of marine life to guide the team to safety, only to face a twist when the treasure seekers turn out to be crooks. Written by Jack Miller and illustrated with dynamic flair by Nick Cardy, this 1962 classic features a standout cover by Sheldon Moldoff.
In "The Mystery of the Undersea Safari," Aquaman and Aqualad answer a call for help when Professor Peters vanishes during a treasure hunt. Guided by the sea’s hidden dangers—rock slides and whirlpools—the duo battles the ocean’s fury, aided by whales and a giant squid, only to uncover a twist that turns their rescue mission into a showdown with deceit.

The Batman lead story was scripted by Bill Finger — Batman's long-uncredited co-creator — and drawn by Sheldon Moldoff with inks by Charles Paris; Moldoff was at this time working as one of Bob Kane's ghost artists, so the issue appeared under Kane's byline even though Moldoff and Finger did the creative work. Jack Schiff served as editor for the Batman and Martian Manhunter features, while the Aquaman short was written by Jack Miller and fully drawn by Nick Cardy. DC did not treat the 300th issue as a special landmark in any overt editorial sense — no anniversary fanfare accompanies the book, which is a standard 36-page anthology — reflecting the era's practice of reserving milestone treatment for round numbers only when they happened to coincide with major story events.
